PROCESS OF LA'STING BOOTS AND SHOES.-

SPECIFICATION forming part of Letters Patent No. 261,602, dated July 25,1882,

Application filed January 21, 1882.

To all whom it may concern:

Be it known that I, GILBERT HAWKES, of Lynn, in the county of Essex andState of Massachusetts, have invented a new and useful-Improvement inthe Process of Lasting Boots and Shoes, of which the following is aspecification.

My invention relates to an improvement in means employed for securingthe uppers 'of boots and shoes to the inner soles in the process oflasting.

Heretofore in the practice of the art the upper has been attached to theinner sole by stitching the two together. Nails and pegs have also beenused for the same purpose. As an improvement upon this'method ofattaching the upper to the inner sole, an adhesive substance has beenemployed, which is spread upon the portion of the upper surface of theinner sole which comes in contact with the upper, and also upontbecorrespondingoverlying edge of the upper, this being done during theoperation of lasting, and the adhesion of the parts so prepared beingeffected by means of pressure. Another means of connecting the upper tothe inner sole consists in the employment of a binding piece or piecesof some thin material, which piece is forcibly pressed down upon theinner sole and the inner edge of the upper, upon each of which (of thetwo latter) has been spread some suitable adhesive mixture-like hotgluc,for instance-the parts being held together until the adhesivematerial dries.

The processes above described occupy considerable time in the operationof lasting, the evaporation of the solvents being requisite in order toeffect the proper setting of the adhesive material.

My invention consists in the process of lasting boots and shoes in whichI employ a textile or other suitable material, such as paper (No model.)

or leather, upon one surface of which is spread a coating of cement ofsuch a nature that when prepared the material will not adhere to any- 5thing with which it comes in contact, and is rendered adhesive only whensubjected to heat sufficient to fuse the cement. The cement employedconsists ot'a combination of shellacgmd iwbber; or it may be composed ofother ingredients which, when used under like conditions, will efiectthe same purpose. When used in the operation of lasting, the material,being cut to theproper size, is placed with its cemented surface uponthe inner sole and the overlying edge of the upper. A heatedpressingtool is then applied to the material, causing the cement to fuseand effecting an instant adhesion of the parts to be united. Thematerial thus prepared may be manufactured and sold in the form shown inFigure 1, adapt-' ed for immediate use.

Fig. 2 is a section of the material on an enlarged scale, B representingthe coating of cement, and 0 the textile or other material upon whichthe cement is spread.

What I claim as my invention is- That improvement in the art of lastingboots and shoes which consists in turning the edge of the upper overupon the inner sole, then applying a fabric coated with a fusible cementadhesive from the action of heat, and attaching the fabric to theinturned edge and to the inner sole by applying heat while the parts areunder pressure, all substantially as set forth.

In testimonywhereof I have signed my name to this specification in thepresence of two sub-.

scribing witnesses.

GILBERT HAWKES.
